We've been trying to keep up with the sightings of all the street art ads that Microsoft has been putting in place in New York City and Los Angeles to promote the launch of the upcoming Surface tablet. Today, yet another such image was spotted in the LA area.

The image was posted on Twitter by E.J. Coughlin, a lead designer for the mobile app company Scopely. As with the other images, it shows a representation of the Surface screen, along with its physical keyboard, and the "Click in" slogan.

The image is a bit different from the other Surface street art ads in two ways. One is that the ad is place on a white brick wall, which makes the image stand out a little bit more than the previous Surface artwork. The other difference is that the ad has been placed on the side of a liquor store.

Specifically, the location is Hudson Liquor & Deli on Melrose Avenue in LA. We do have to wonder if the patrons of Hudson are the intended target audience for the upcoming Windows 8/RT tablet from Microsoft.

We will be keeping you up to date if and when any other Surface street art ads pop up.
